Method 1

Unfortunately it is at the moment not possible to color text of a Slack message with the API. You can use different styles, e.g. bold and italic, but not colors.

You can use colors for your attachments. That will however result in a vertical color bar marker for the whole attachment, but not in colored text.

Here is an example on how to use colors for Slack attachments (taken from the Slack documentation):

{
    "attachments": [
        {
            "fallback": "New ticket from Andrea Lee - Ticket #1943: Can't rest my password - https://groove.hq/path/to/ticket/1943",
            "pretext": "New ticket from Andrea Lee",
            "title": "Ticket #1943: Can't reset my password",
            "title_link": "https://groove.hq/path/to/ticket/1943",
            "text": "Help! I tried to reset my password but nothing happened!",
            "color": "#7CD197"
        }
    ]
}

Method 2

What you can do (as an admittedly clumsy workaround until/unless Slack supports more than primitive formatting) is:

  • Create your message as a small graphic image on your server
  • upload the image’s web address to the slack channel using the webhook
  • the message is now displayed in channel

You can use ImageMagick for this.

.png images allow for transparency, so you don’t have to worry too much about background matching.

This is, of course, a terribly inefficient way to go about it, but it has the agreeable characteristic of doing what you want.
